When we last left off with The Last Man on Earth, we caught a quick glimpse of Fred Armisen as he made his debut on the brilliant, touching and funny sitcom. Tonight at 9:30p on Fox, we get to learn a lot more about his character Karl in a standalone episode.

Karl is a guy who lives on his own. The type of guy who goes out on dates with a Leighton Meester type, but goes home all by himself.

Then one day he makes a mistake and he flees to Mexico to start a new life. On the way there, he meets our special guest star of the night and they share an unforgettable moment. When he settles in Mexico, he begins his new life. Just when he decides to change his ways, the virus happens. Now everyone around him is dead and he is living all by himself.

That is until Tandy (Will Forte) and Tood (Mel Rodriguez) find him. What happens next, we will have to wait until next week to find out.

What I am not telling you, is why I will never be able to look at Armisen the same way. Why? You will just have to tune in to find out. Not only for that but all because LMOE is a witty comedy with so much heart, it will leave you starting the work week off with a huge smile on your face. As long as you don’t hone in on the fact that it is post-apocalyptic show about a virus that wiped out almost everyone on Earth and the few survivors are trying to repopulate the world. Survivors who get to live out some of their fantasies because who is going to stop them? See a fell good way to end your Sunday nights.
